JAMES SIVAN, OF CHICAGO, ILLINOIS.

BOLTlNG-REEL.

SPECIFICATION forming part of Letters Patent No. 420,761, dated J' une 24, 1890.

Application filed September 24, 1888. Serial No. 286,213. (No model.)

To all whom it may concern.:

Be it known that I. JAMES SWAN, a citizen.

i invented a new and useful Bolting-Reel, of

which the following is a specification.

My invention relates to devices for bolting Iiour and the like in mills and elsewhere, and has for its object to provide a cheap, simple, and effective bolt-ing-reel wherein the stock has a sliding motion over the greater part of the surface of Jthe bolting-cloth and is not to any considerable extent forced or thrown against it. This objectI accomplish by means of the mechanism illustrated in the accompanying drawings, wherein- Figure l is an end view of the case containing my device. Fig. 2 is a similar view of the end of the driving mechanism removed, so as to show the interior of the reel and tail-board. Fig. 3 is a longitudinal section through the reel. Fig. I is a cross-section through the saine. Fig. 5 is a detail of one of the pockets.

Like parts are indicated by the same letter in all the figures.

A A are the frame-timbers; B, the drivingpulley; C, the shaft on which such pulley is secured.

C is a trunnion.

D is the tail-board at the end of the reel.

F is a bar or timber through the center of the reel and journaled at its extremities by the trunnion C and shaft C, which respectivcly rest in the bearings C2 C3.

G G are bolts or rods, which are secured to the bar F and at the outer extremities to the longitudinal frame-pieces H II of the reel.

The reel is composed of the frame pieces II Il, the longitudinal side frame pieces I I, and the curved bars .I J, to which these longitudinal frame-pieces are secured.

The reel rotates within the box K and carries at its extremity the tail-board D.

Attached to the frame-pieces II II and lying between them are the outwardly-curved pockets L L, and on the remainder of the interior 0f the surface of the reel is the boltingcloth M M. Below is fixed the conveyer-box N, the operative parts of which are driven by the chain O from the sprocket-wheel I). At thc side of the box K is placed the supply pipe R, which delivers the stock within the reel.

The size and shape of the reel and the width, depth, and material of the pockets L could be greatly varied without departing from the spirit of the invention.

The use and operation of my invention are as follows: The stock is introducedthrough the supply-pipe R within the reel, the reel being slightly inclined downward ly away from the side vat which the pipe introduces the stock. The stock naturally falls sooner or later to the bottom ofthe reel, and, assuming that the reel is in the position shown in Fig. 4., this stock will fall into one of the pockets L and by the motion of the reel will usually be kept distributed from end to end in the said pocket. If now the rcel begins to move or continues its motion in the direction indicated by the arrow in Fig. J., the stock will remain in the pocket L until a considerable portion of the revolution has been made, when, if the revolution be properly timed, the stock will begin to slide down over the cloth Maud will reach the neit pocket L just as the same assumes the position shown in Fig. I. In this manner it will be seen that the stock slides over one-half the surface of the cloth at each half-revolution; or, in short, that it slides over the entire surface of the cloth every revolution. WVhen the stock begins to slide, which it usually does when the pocket has moved through one-quarter of the circle from its lowest point, the descent of thc stock along the cloth will be very gradual, and as the motion continues its velocity will increase until it reaches its maximum just as the next pocket reaches the lowest point in its revolu tion, as will be readily seen by inspection of Fig. 4. Into this pocket it descends with con siderable velocity; hence the necessity of forming this pocket of a more or less unyielding -substance-as, for instance, a metallic plate-though, of course, cloth or other material could be used. The velocity of the revolution of this reel is very slow. As the flour or stock passes through the cloth it is carried in the usual manner into the conveyers and passed on to thesuccessive processes.

By the peculiar shape or form of the reel which carries the bolting-cloth the stock is IOC) made to slide from one of the pockets or depressions L L to the other along the inner surface of the reel; or if the pockets LL Were dispensed with all or substantially all of the stock Would have the same sliding motion along the inner surface of the reel from end to end thereof. To secure this action, it is only necessary to properly time the revolutions of the reel, as When so timed the curve of the reel is such as to present a comparatively uniform angle of descent to the stock as it passes down along the surface of such rcel. The stock is not dropped from point to point along the reel. Neither is it rubbed upon the surface of the cloth; but is given, as above described, a gentle sliding motion on the surface of the cloth on the inside of the reel.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is as follows:

l. In a bolting-reel, the combination of a frame With a longitudinal axis, a bolting-elotl1 cove-r, and Widely-separated longitudinal pockets depressed below the inner surface of the cloth, so that the material is gathered therein and then permitted to slide on the even surface as the reel rotates.

2. In a bolting-reel, the combination of a frame oblong` in cross-section With a longitudinal aXis, a bolting-clothicover, and longitudinal pockets situated at the extremities of its longest transverse axis and depressed below the surface of the cloth.

3. In a bolting-reel, the combination of a frame with a longitudinal aXis, a bolting-cloth cover, and Widely-separated longitudinal pockets depressed below the inner surface of the cloth, so that the material is gathered` therein and then permitted to slide on the even surface as the reel rotates, said pockets being formed of imperforate material.
